Flame, weeping, christmas, peacock, etc... Are they generally as hardy as good old java moss? I really want to try something different in the vaillanti setup, but don't want to put down on something that's not gonna end up growing. So sick of looking at clumps of java moss though, it's not even funny. Do you think the weeping and flame type of mosses would do well in a blackwater setup with just over 1 wpg and maybe some excel now and then?
